Description

Technical Field:

[0001] The utility model relates to the technical field of heat exchanger processing equipment, and more specifically to a heat exchange oil tank device for an oil cooler. Background Art:

[0002] In current mechanical equipment, engine oil is provided inside for the normal operation of mechanisms such as gearboxes. However, during operation, its temperature will continuously rise and cooling is required. Existing cooling methods are either directly blowing air on the equipment's oil tank for cooling or passing through heat exchange tubes with circulating water for heat exchange. For direct air blowing for heat dissipation, the cooling effect is limited. For directly installing heat exchange tubes in the oil tank for heat exchange, it occupies the internal space of the oil tank, greatly reducing the oil storage capacity of the equipment's oil tank and affecting its oil storage effect.

[0003] Therefore, an external device is needed to output the oil in the oil tank for heat exchange and then return it to the equipment's oil tank. In existing external heat exchange oil tanks, a heat exchange tube is inserted into a rectangular or cylindrical oil tank for heat exchange. The distance between the heat exchange tube and the inner side wall of the oil tank is large, resulting in low heat exchange efficiency. Moreover, the oil flows within a rectangular or cylindrical oil tank, with a small flow range and low heat exchange efficiency. Summary of the Utility Model:

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a heat exchange oil tank device for an oil cooler. It adopts an oil tank main body that is in a U - shaped configuration when viewed from above, and an evaporator is arranged inside to cooperate with it, thereby improving the heat exchange efficiency. At the same time, the main liquid outlet pipe is located above the front end of one side's side - extending box - body part, and the oil return connection pipe head is located at the front end plate of the other side's side - extending box - body part. The distance between the two is increased, enhancing the oil flow distance, and thus improving the heat exchange effect and efficiency.

[0005] The solution for the utility model to solve the above - mentioned technical problems is as follows:

[0006] A heat exchange oil tank device for an oil cooler includes a bottom plate. A U - shaped oil tank main body when viewed from above is fixed on the top surface of the bottom plate.

[0019] Embodiment, as shown inFigures 1 to 3 As shown in the figure, a heat exchange oil tank device for an oil cooler includes a bottom plate 10. On the top surface of the bottom plate 10, a tank body 20 is fixed, which is in a U-shaped configuration when viewed from above. It includes two side extension box body parts 21 extending forward and backward on the left and right, and a transverse box body part 22 at the rear between the two side extension box body parts 21. The left and right ends of the transverse box body part 22 communicate with the rear parts of the two side extension box body parts 21. (The side extension box body parts 21 and the transverse box body part 22 can be directly formed into an integral structure by means such as bending and welding steel plates. At this time, the transverse box body part 22 is formed between the rear parts of the two side extension box body parts 21 and is in communication. The top cover 23 is fixedly connected to the tops of the side extension box body parts 21 and the transverse box body part 22 by bolts and covers the top of the inner cavities of the side extension box body parts 21 and the transverse box body part 22. At the same time, a sealing strip is clamped between the top cover 23 and the top surfaces of the side extension box body parts 21 and the transverse box body part 22 to achieve sealing). An evaporator main component 30 is installed in the tank body 20. The evaporator main component 30 is also in a U-shaped configuration when viewed from above and is matched with the tank body 20.

[0020] A main liquid outlet pipe 24 is connected to the top cover 23 of the tank body 20. At the lower part of the front end plate of one of the side extension box body parts 21 of the tank body 20, an oil return connection pipe head 25 is connected. The main liquid outlet pipe 24 is above the front end of the side extension box body part 21 on one side, and the oil return connection pipe head 25 is at the front end plate of the side extension box body part 21 on the other side.

[0021] A first through hole is formed in the top cover 23 of the tank body 20 at the bottom end of the main liquid outlet pipe 24. A pipe connection sleeve is located in the first through hole, and the outer side wall of the pipe connection sleeve is welded and fixed to the inner side wall of the first through hole. The bottom of the main liquid outlet pipe 24 is clamped in the pipe connection sleeve and communicates with the tank body 20.

[0022] Furthermore, a first plug 1 is screwed to the oil return connection pipe head 25. During use, after removing the first plug 1, the oil return connection pipe head 25 can be connected to the oil outlet of the oil tank of the equipment through a connecting pipe. The liquid outlet of the main liquid outlet pipe 24 can be connected to an oil pump, and the liquid outlet of the oil pump is connected to the oil inlet of the oil tank of the equipment. By operating the oil pump, the circulation of the oil can be realized. The oil can enter the oil tank of the equipment through the main liquid outlet pipe 24 via the oil pump. Then, the oil in the oil tank of the equipment flows into the tank body 20, where it exchanges heat with the evaporator main component 30 in the tank body 20 to reduce the oil temperature.

[0023] Among them, the refrigerant inlet and outlet of the main evaporator component 30 extend out of the oil tank main body 20 and can be connected to a refrigeration device (the refrigerant inlet of the main evaporator component 30 is connected to the capillary outlet or throttle valve outlet of the refrigeration device, and the outlet of the main evaporator component 30 is connected to the inlet of the compressor. Refrigeration components such as the compressor can be installed in the middle of the top surface of the bottom plate 10), enabling the flow of refrigerant, and thus heat exchange and cooling with the oil can be achieved.

[0024] Furthermore, the oil tank main body 20 includes a main box body 26 and a top cover 23. The top cover 23 is fixedly connected to the top end of the main box body 26 by bolts. Lower support frames 231 are fixedly arranged on the bottom surfaces of the left and right sides of the top cover 23. The left and right parts of the main evaporator component 30 are fixed on the two lower support frames 231. This structure ensures that the bottom of the main evaporator component 30 does not contact the top surface of the bottom plate of the main box body 26, guaranteeing the normal flow of the oil.

[0025] Furthermore, the main evaporator component 30 includes a heat exchange tube 31 coiled in an S shape and a plurality of heat dissipation fins 32 fixed on the outer side wall of the heat exchange tube 31. The left and right parts of the heat exchange tube 31 are bent to form a left bent part and a right bent part, and the left bent part and the right bent part are inserted into the corresponding side extension box body parts 21. The middle part of the heat exchange tube 31 is located in the transverse box body part 22 of the oil tank main body 20.

[0026] Furthermore, an oil injection connection head 27 is fixed on the upper front wall surface of the front end plate of one side extension box body part 21. An inclined oil inlet hole is formed on the oil injection connection head 27, which is communicated with the through hole in the upper part of the front end plate of the corresponding side extension box body part 21.

[0027] Furthermore, an oil discharge connection pipe head 211 is connected to the front end plate of the side extension box body part 21 at the lower part of the oil injection connection head 27, and an oil discharge plug 2 is screwed on the oil discharge connection pipe head 211.

[0028] Furthermore, a liquid level gauge 3 is fixed on the front wall surface of the front end plate of one side extension box body part 21, and the liquid level gauge 3 is communicated with the side extension box body part 21. The oil condition in the oil tank main body 20 can be checked through the liquid level gauge 3. The cover head screwed on the oil injection connection head 27 can be opened as needed to supplement the oil from the oil injection connection head 27.

[0029] By opening the oil discharge plug 2, oil discharge can be achieved.
